Doordie,
Have you measured how much it pulls the front axle back compared to the stock offset?? I have always wanted more frontend "Bite" out of the KX. I bought a set of clamps with 1/2 degree less rake and it made a very small difference (axle distance 1/2 inch shorter measured axle to axle). As CR37 said, the Dog Bones have made the biggest difference for me, used the Pro Circuit (1mm shorter) and the Devol (adjustsable +1,0,-1,-2).
